Full Stack Engineer

About the Position

Your vision. Our solutions.

We're seeking a Senior Software Engineer to join our team in Prague, Czech Republic, building a cloud-native platform for clinical trial data standardization.

Responsibilities

• Design and extend the SDTM transformation engine - AWS Step Functions orchestration, Lambda workers, and Databricks write paths
• Build and evolve the GraphQL/AppSync API and React frontend used by analysts to author mapping specifications
• Own infrastructure-as-code changes across service Terraform stacks and shared infrastructure
• Participate in code review, architecture discussions, and on-call rotation
• Mentor engineers newer to the stack or clinical data domain

Requirements

Must-Have

• 7+ years of professional software engineering experience
• Python proficiency - you're comfortable with Lambda Powertools, pytest/pytest-bdd, and writing clean, testable Python in a monorepo context
• AWS depth: Lambda, Step Functions, S3, DynamoDB, and IAM - you can reason about cost, latency, and failure modes, not just get things working

Strong Plus

• GraphQL / AppSync experience - schema design, resolvers, and consuming AppSync from a React client
• React + TypeScript - comfortable contributing to a Vite/Cloudscape SPA without being a frontend specialist
• Infrastructure as code with Terraform - reading, writing, and debugging multi-stack configurations
• Databricks or similar large-scale data processing platforms
• Clinical data standards (CDISC SDTM, ADaM) or regulated-industry software development experience (GxP, 21 CFR Part 11)
• A good grasp of event-driven and distributed system patterns - fan-out/fan-in, idempotency, at-least-once delivery

How You Work

• You write code that is easy to delete, not just easy to read - you don't over-engineer
• You're comfortable tracing a bug across Lambda logs, Step Functions execution history, and DynamoDB state without being told where to look
• You communicate clearly in async environments and leave PRs and architecture decisions well-documented for the people who follow you
• You can context-switch between a Python data pipeline and a TypeScript component without losing momentum

We Offer

• Competitive salary
• Hybrid work model
• Opportunity to work on meaningful domain impact projects
